Upon reflection, with these types of damage, fire/cold/electrical/acid/sonic, the character becomes almost immune to unfeated spells.
Damp Power looks better on paper than it is in reality when compared to Intellect Fortress.
Damp Power is real effective against one spell or power per round. But, that's the problem with it. One per round. Intellect Fortress can protect against multiple spells or powers.
For example: 10D6 Fireball averages 35 points of damage
A Psion with Intellect Fortress takes 17 or 8.
A Psion with Damp Power takes 10 or 5.
So yes, if only one 10th caster level spell is thrown at the Psion, then he takes 3 or 7 average points less of damage with Damp Power than with Intellect Fortress in this case. But, if a second spell is thrown, he takes 5 to 10 more, and if a third one is thrown he takes 13 to 27 more, etc.
Plus, if a Psion uses this in a given round, he cannot use any other swift or immediate action. This is also true for round one of Intellect Fortress, but not for other rounds (and most Psions will probably put more than 7 PP into Intellect Fortress, just to get the multi-round protection).
Plus, Intellect Fortress protects against spells and powers that do not do variable damage, so Maximize does not negate it. And, Intellect Fortress protects against ability damage, even if it is not a variable numeric effect. And, Intellect Fortress will work in a Lesser Globe of Invulnerability (but not a normal one). And, for Warforged Psions like my future one in our next campaign, Intellect Fortress protects against Disable Construct. Damp Power does not.
Damp Power, on the other hand, will work against Orb spells, Intellect Fortress will not. And, Damp Power can be used at 3rd level and only costs 3 PP for the Psion Only protection. And, Damp Power can protect against spells and powers which do not do damage, but have other variable numeric effects.
So sure, Damp Power is a good defense against certain attacks. But, Intellect Fortress is typically better overall. Given a choice between the two, I would take Intellect Fortress for two reasons: I can put it up for more than one round cheaply, and I can have the protection and still use swift or immediate actions in latter rounds. For a Psion, swift and especially immediate actions are important.
Course, this is only true in a transparent Psionic / Magic campaign.
Note: Intellect Fortress can have the downside of protecting the Psions enemies as well, but that is dependent on situation and how tactically well one plays the Psion.
